I purchased a flash drive for my Iphone. It would not work. I paid to ship back and assumed refund would follow. Ebay sent email asking if refund occurred. I checked, it did not. Ebay said too bad, case closed. I closed account. Have had friends/neighbors with similar situations, my case was low cost. Lesson learned. I was lucky up to today. I will not chance luck again. I conduct business with reputable organizations.
